Kernel PTI disabled

Question regarding kernel PTI. In the advanced options, I do NOT check the box "Disable the kernel PTI." My understanding is that in this case kernel PTI is ENABLED. Yet under system information on the dashboard, Kernel PRI is listed as DISABLED. Is this a bug in pfsense or in my head?

Thank you for the responses and the key pointer. I totally "forgot" that the pfsense instance in question is indeed running on an AMD APU, which is not sensitive to the metldown bug addressed by this setting. Case closed.
